Table 6 Circumference and perceived muscle pump data of 19 resistance trained men receiving placebo or supplement in a cross-over design.

From: Comparison of pre-workout nitric oxide stimulating dietary supplements on skeletal muscle oxygen saturation, blood nitrate/nitrite, lipid peroxidation, and upper body exercise performance in resistance trained men
